Abstract
The present invention relates to a data exchange method and apparatus. The method includes: sending, by a primary base station, a request of setting up an X3 interface to a secondary base station, wherein the X3 interface has a capability of bidirectional data communication; receiving, by the primary base station, a response of setting up the X3 interface sent by the secondary base station; and performing, by the primary base station, bidirectional data exchange with the secondary base station by using the X3 interface.
Claims9
A data exchange apparatus, comprising:
- a transmitter configured to send a request of setting up an interface to a secondary base station, wherein the interface has a capability of bidirectional signaling communication;
- a receiver configured to receive a response of setting up the interface sent by the secondary base station;
- a processor configured to perform bidirectional signaling exchange with the secondary base station by using the interface;
- and
- wherein the transmitter is further configured to:
- send a downlink transport network layer (TNL) address and a General Packet Radio Service Tunneling Protocol tunnel endpoint identifier (GTP TEID) of the secondary base station to a user plane entity by using a mobility management entity (MME), and
- send an uplink TNL address and a GTP TEID of the user plane entity to the secondary base station.
